COLLAR- BUTTON.

SPECIFICAIION forming part of Letters Patent No. 714,937, datd December 2, 1902. Application fiied March 18, 1902. Serial No. 98.854. (No model.)

T0 all whont it may c0ncern:

Be it known that I, BRUCE MURPHY, a sub ject of the King of Great Britain, residing at Oriliia, in the Province of Ontario and Dominion of Canada, have invented new and nsefn1 Improvements in Collar-Buttons, of which the foilowing is a specification.

This invention relates to improvements in collar-buttons, and has speciai reference to that type in which a fiat head is adapted to be swung into the same plane as a fiat shank on which it is mounted, whereby both may be passed through the buttonhole and the head then swung at right angles to the shank to lie across the buttonhole and to provide an overhanging part under which the tie may be caught, if desired, 'when the stud is used at the back instead of at the front of the collar.

The invention consiste in a construction of a stud of the character described in a simplified form, all as fu1ly set forth in the following specification and carefully pointed out in the claims.

In the drawings forming part of this application, Figure 1 is a sectional elevation of a collar-button embodying my invention, the section on which it is taken being indicated by the line 1 1, Fig. 2. Fig. 2 is a side clevation of Fig. 1 in a plane at right angles to the plane of the latter. Fig. 3 is a plan view looking down on Fig. 2. Fig. 4 is a plan view looking toward the lower side of Fig. 2, a portien of said lower side being broken away. Fig. 5 is a perspective view of a washer forming part of my improved construction, and Fig. 6 is a perspective view et a spring.

The buttons shown in the drawings are all larger than naturai size.

The shank of the button is indicated by a and has at one end thereof an annnlar fiange I). The shank is of fiattened tubular form, as shown in the drawings, and the extremity thereof opposite to its fianged end is closed, as is clearly shown in Figs. 1 and 3, and in said closed end there is a depression 0, extending transverseiy across it, having a Width siightiy greater than the transverse dimension of the shank. Centraliy of said closed end there is an aperture through which the end of a post d projects, to which is secured in anysuitabie manner ahead or bar 6, which, preferably, is so formed as to constitute a proper end piece for the shank a, to the end that when it is swung into paraileiism therewith it wiil appear to be but a continuation thereof. This head eis struck up from sheet metal and is so secured to the post d as to leave a siight concavity at the under side thereof, and the ciosed end of the shank ais se formed as to be slightly crowning, to the end that when the head e is substantially in parallelism With the shank it will fit over this crowning end thereof and be prevented from readily turning thereon. When, on the other hand, it is swung around into the position shown in Figs. 1, 2, and 3, the edges of said head will ride up on said crowning portions of the end of the shank until the head reaches a position substantially at right angles to the shank, at which point said head wili drop into the before-mentioned depression a.

A close contact between the head 6 and the shank a is maintained by means of a spring f, (which is shown in perspective view in Fig. 6,) which engages the end of the post (1, as shown. This spring is supported only byits ends and bridges the hollow shank, to the end that as the head 6 is swung on the post d the tension et the spring Will cause said head either t0 snap down over the crowning end of the shank when in position to do 80 or snap in the depression c when in position to enter it.

The completed button is shown in side clevation. in Fig. 2, and this view (and Fig. 1) shows the back g put on in the usual manner by being crimped over the fiange b on the shank of the button.

It will be observed that a circular washer h is located in the cavit y formed by the fiange b on one end of the shank of the button. This washer is centrally perforated to allow the post d to move freely endwise therethrough when the head is Lurned relative to the shank, as described. The purpose of this washer h is primarily to protect the spring f against any undue strain and is slightly cupped, as shown, to such a degree as Wil1 permit the spring to be subjected to a degree of flexure which wili net cause said spring to set. The spring fobviously cannot be a very rigid one, and therefore if the head 6 were to be puiled away from the shank the spring might be very easily broken or set without sonne means, as said washer, for preventing this.

There are a number of ways in which the proper conneotion might be effected between the ends of the post 01 and the springf. The preferred mannerof constructing these parts is to turn down the end of the post to form a narrow neck l:, leaving on the end of said post a head j, thon forming a suitable slot, as 16, in the springf, Which slot is narrower than the headj on the end of the post, and then by passing the neoked-down portion 2' of the post into this slot in the spring it is seen that the post Will thereby be held under endwise tension. The ends of the springf, as shown in Fig. 1 particularly, rest on the borders of the washer h at opposite points, the spring bridging the conoavity of said washer. This washer is aotually a non-essential element, for the ends of the spring might rest at opposite points on the flange Z), and the button would thon operate to all intents and purposes as it does when constructed as shown in the drawings; but, as stated, there is the 1iability of breaking the spring when the device is constructed without said washer; but this, however, might be provided against in sorne other way than by the use of the washer. To the end that the spring f may operate properly the s1ot le chemin extends practically to the center of the spring, at whioh point the post dis suspended thereon, and the opposite end of the spring is likewise slotted, to the end that one portion of' said spring may not be much more rigid than another. The Washer h, being concaved, as shown,sarves still another useful purpose,viz: Its surface serves as a guide for the spring fwhen the latter is to be slipped over the necked-down portion of the post d, as this operation necesstas the fiexure of the spring, which latter is easil y accomplished by holding it by one of its ends and pressing the other down against the oonoaved surface of the washer, whereby the divided ends of the spring are easily slipped into engagement With the portion of the post d referred to.

IIaving thus descrbed my invention, what I claim, and desire to seoure by Letters Patent of the United States, is

1. In a collar-bntton, the combinaton with the flattened tubular shank of a button having a orowning closed end, there being a depression in said end transversely thereof, of a post in said shank, a head secnred thereto, constitutng, when in one position, a continnation of said shank, said head and post being revolnble; a cnpped disk looated transversely in the shank having an aperture theroin for said post, and a fiat spring spanning said disk and having a connection with said post.

2. In a collar-butt0n, the combination with the fiattened tubular shank of a button having a crowning closed end, there being a depression in said end transversely thereof, of a post in said shank, a head secured theret0 constitnting, when in one position, a continuation of said shank, said head and post being revoluble; a forked spring supported by its ends on the fianged end of the shank, and a head on said post under which the forks of said spring may pass to support the post in operative position.

3. In a collar-button, the combination With the fiattened tubular shank 01: a button having a crowning closed end, there being a depression in said end transversely thereof, of a post in said shank, a head seenred thereto constituting, when in one position, a continuation of said shank, said head and post being revoluble; a forked spring supported by its ends on the flanged end of the shank, and a head on said post under which the forks of said spring may pass to support the post in operative position, et washer through which the spring-engaged end of the post passes, and whereby the movements of the spring are limited.

BRUCE MURPHY.
